[0072] The liquid outlet device provided in the embodiment is used for automatic vending equipment, for example, automatic vending and automatic liquid outlet of liquid such as sugar liquid, tomato sauce, oil, and honey.

[0073] Referring to Figures 1-13 The liquid outlet device provided in the embodiment includes a shell 100, a driving device 200, a shielding device 500, and a liquid bottle 300 with a pump head 310; the driving device 200 and the liquid bottle 300 are respectively arranged inside the shell 100.

[0074] The driving device 200 is drivingly connected to the liquid bottle 300, and under the reaction force of the shell 100, the pump head 310 of the liquid bottle 300 can be squeezed. In the embodiment, the driving device 200 can be arranged at the top of the liquid bottle 300 or at the bottom of the liquid bottle 300.

[0075] The shell 100 is provided with a shell liquid outlet hole 110, and the shell liquid outlet hole 110 cooperates with the liquid outlet end of the pump head 310; that is, the liquid in the liquid bottle 300 is sequentially discharged through the liquid outlet end of the pump head 310 and the shell liquid outlet hole 110.

[0076] The shielding device 500 is connected to the shell 100, and the shielding device 500 can shield or be away from the shell liquid outlet hole 110, that is, the shielding device 500 can shield or be away from the liquid outlet end of the pump head 310. Through the shielding device 500, the shell liquid outlet hole 110 can be shielded during non-working time, and thus the liquid outlet end of the pump head 310 is shielded, and the time length of the liquid outlet end of the pump head 310 exposed to the air is reduced.

[0077] When the pump head 310 of the liquid bottle 300 is squeezed by the driving device 200, the shielding device 500 is away from the shell liquid outlet hole 110 and exposes the liquid outlet end of the pump head 310.

[0078] When the pump head 310 of the liquid bottle 300 is in the initial position, the shielding device 500 shields the shell liquid outlet hole 110, thereby shielding the liquid outlet end of the pump head 310.

[0079] Optionally, the amount of liquid discharged each time can be controlled by selecting the pump head 310 of the liquid bottle 300 of different specifications.

[0080] Optionally, when the liquid discharging device in the embodiment is in a non-working state, the pump head 310 of the liquid bottle 300, the driving device 200 and the shielding device 500 are in the initial position; at this time, the pump head 310 of the liquid bottle 300 is in a non-extrusion state, and the shielding device 500 is in a state of shielding the shell liquid outlet hole 110. Optionally, when the liquid discharging device is in a non-working state, the driving device 200 is in a retracted state.

[0081] Optionally, when the liquid discharging device in the embodiment is in a working state, the pump head 310 of the liquid bottle 300 is in an extrusion state, and the shielding device 500 is in a state of moving away from or moving away from the shell liquid outlet hole 110. Optionally, when the liquid discharging device is in a working state, the driving device 200 drives the liquid bottle 300 to move and extrude the pump head 310 of the liquid bottle 300, the pump head 310 of the liquid bottle 300 is pressed against the shell 100 and cannot move, and then is compressed, the pump head 310 is compressed once, and the liquid is pumped out once; after the liquid is discharged, the driving end of the driving device 200 starts to retract, the pump head 310 starts to rebound under the action of the internal spring, and after the driving end of the driving device 200 is retracted, the pump head 310 is also rebounded, and waits for the next round of liquid discharging action.

[0082] The liquid discharging device in the embodiment includes a shell 100, a driving device 200, a shielding device 500 and a liquid bottle 300; the liquid bottle 300 is driven by the driving device 200 to extrude the pump head 310 of the liquid bottle 300, so as to realize the liquid discharging of the liquid in the liquid bottle 300, the automatic liquid discharging mode is replaced at low cost, and the complex pipeline when the peristaltic pump is used to extract the syrup is avoided; the shielding device 500 can shield or move away from the shell liquid outlet hole 110 of the shell 100, that is, the shielding device 500 can shield or move away from the liquid outlet end of the pump head 310, so that the shielding device 500 can shield the liquid outlet end of the pump head 310 during non-working time, and reduce the time length of the liquid outlet end of the pump head 310 exposed to the air; by moving away from the shell liquid outlet hole 110 and exposing the liquid outlet end of the pump head 310 when the pump head 310 of the liquid bottle 300 is extruded by the driving device 200, the shielding device 500 moves away from the liquid outlet end of the pump head 310 during working time, so as to facilitate the smooth liquid discharging of the liquid outlet end of the pump head 310.

[0083] Referring to Figures 2-4 In the optional scheme of the embodiment, the pump head 310 of the liquid bottle 300 abuts against the top of the shell 100.

[0084] The driving end of the driving device 200 abuts against the bottle bottom of the liquid bottle 300, and the driving end of the driving device 200 drives the connection of the shielding device 500; the fixed end of the driving device 200 is connected with the shell 100. The liquid outlet equipment in the embodiment can effectively reduce the volume of the upper part of the liquid outlet equipment, simplify the structure of the upper part of the liquid outlet equipment, and facilitate the taking and replacement of the liquid bottle 300 from the top of the shell 100, by arranging the driving device 200 at the bottle bottom of the liquid bottle 300 and using the jacking mode to press the pump head 310 of the liquid bottle 300 to outlet liquid.

[0085] The driving device 200 is configured to drive the bottle bottom of the liquid bottle 300 to move towards the pump head 310 of the liquid bottle 300, and simultaneously drive the shielding device 500 to move away from the shell liquid outlet hole 110, so that the pump head 310 of the liquid bottle 300 abuts against the top of the shell 100 and presses the pump head 310 of the liquid bottle 300. The driving device 200 simultaneously drives the liquid bottle 300 and the shielding device 500 to form a linkage relationship, so as to facilitate the liquid outlet of the liquid bottle 300.

[0086] Referring to Figures 2-6 In an optional solution of the embodiment, the driving end of the driving device 200 has an initial position and a jacking position; for example, the jacking position is the maximum position or a larger position of the movement of the driving end of the driving device 200, and the initial position is a position where the driving end of the driving device 200 has not been extended.

[0087] Optionally, when the driving end of the driving device 200 moves from the initial position to the jacking position, the bottle bottom of the liquid bottle 300 moves towards the pump head 310 of the liquid bottle 300 and presses the pump head 310 of the liquid bottle 300, and the shielding device 500 moves away from the shell liquid outlet hole 110 and exposes the liquid outlet end of the pump head 310, so that the liquid in the liquid bottle 300 is sequentially outletted from the liquid outlet end of the pump head 310 and the shell liquid outlet hole 110.

[0088] Optionally, when the driving end of the driving device 200 moves from the jacking position to the initial position, the pump head 310 of the liquid bottle 300 drives the bottle bottom of the liquid bottle 300 to reset, and the shielding device 500 shields the shell liquid outlet hole 110, so that the pump head 310 of the liquid bottle 300 and the shielding device 500 return to the initial position and wait for the next liquid outlet.

[0089] Referring to Figure 5 , Figures 7-10 In an optional solution of the embodiment, the shielding device 500 includes a first connecting piece 510, a second connecting piece 520, a connecting boss 540, and a liquid outlet baffle 550.

[0090] The first connecting piece 510 comprises a corresponding first end and a second end; the driving end of the driving device 200 drives the first end of the first connecting piece 510; and the second end of the first connecting piece 510 is fixedly connected with the connecting boss 540. For example, the second end of the first connecting piece 510 is fixedly connected with the connecting boss 540 through screwing, welding, bonding or inserting and the like.

[0091] The end of the second connecting piece 520 abuts against the connecting boss 540; and the liquid outlet baffle 550 is fixedly connected on the second connecting piece 520.

[0092] The first connecting piece 510 and the second connecting piece 520 are both slidably connected with the shell 100; that is to say, the first connecting piece 510 can slide relative to the shell 100, and the second connecting piece 520 can slide relative to the shell 100.

[0093] The driving device 200 can drive the first connecting piece 510 to move, so that the connecting boss 540 abuts against the second connecting piece 520 and drives the second connecting piece 520 to move, and then drives the liquid outlet baffle 550 to move away from the shell liquid outlet hole 110, and then exposes the liquid outlet end of the pump head 310.

[0094] Optionally, when the driving end of the driving device 200 moves from the initial position to the jacking position, the driving device 200 can drive the first connecting piece 510 to move, so that the connecting boss 540 abuts against the second connecting piece 520 and drives the second connecting piece 520 to move, and then drives the liquid outlet baffle 550 to move away from the shell liquid outlet hole 110, and then exposes the liquid outlet end of the pump head 310.

[0095] Optionally, when the driving end of the driving device 200 moves from the jacking position to the initial position, the driving end of the driving device 200 is retracted, the first connecting piece 510 can move and reset under the driving of the driving device 200 and / or the driving of the elastic force, and the liquid outlet baffle 550 can reset with the second connecting piece 520, so that the liquid outlet baffle 550 blocks the liquid outlet end of the pump head 310. Optionally, the second connecting piece 520 can reset under the driving of the elastic force; for example, when the driving end of the driving device 200 moves from the initial position to the jacking position, the second connecting piece 520 moves and compresses the elastic piece, and when the driving end of the driving device 200 moves from the jacking position to the initial position, the second connecting piece 520 is retracted and reset under the elastic restoring force of the elastic piece due to the removal of the external force of the connecting boss 540 on the second connecting piece 520.

[0096] Optionally, the first connecting member 510 can move and reset under the drive of the driving device 200; for example, the first connecting member 510 is fixedly connected to the driving end of the driving device 200 so that the first connecting member 510 moves synchronously with the driving end of the driving device 200; when the driving end of the driving device 200 retracts and resets, the first connecting member 510 also retracts and resets.

[0097] Optionally, the first connecting member 510 can move and reset under the driving force of elastic force; for example, when the driving end of the driving device 200 moves from the initial position to the jacked-in position, the driving device 200 drives the first connecting member 510 to move and compress the elastic member. When the driving end of the driving device 200 moves from the jacked-in position to the initial position, the external force exerted on the first connecting member 510 by the driving device 200 is removed, and the first connecting member 510 retracts and resets under the action of the elastic restoring force of the elastic member.

[0098] Optionally, the first connecting member 510 can move and reset under the drive of the driving device 200 and the elastic force; through the dual effects of the driving external force and the elastic force, the retraction and reset of the first connecting member 510 is effectively guaranteed, and the retraction and reset speed of the first connecting member 510 is improved.

[0099] See also Figure 8 and Figure 10 As shown, in an optional solution of this embodiment, the side surface of the connecting boss 540 includes an inclined surface portion 541 and a straight surface portion 542 connected to each other.

[0100] When the driving end of the driving device 200 is at the initial position, the inclined surface portion 541 abuts against the second connecting member 520 ; when the driving end of the driving device 200 is at the lifted position, the straight surface portion 542 abuts against the second connecting member 520 .

[0101] When the driving end of the driving device 200 moves from the initial position to the jacking position, the connecting boss 540 moves with the first connecting piece 510, the inclined surface part 541 abuts against the second connecting piece 520 and drives the second connecting piece 520 to move, so that the liquid outlet baffle 550 moves with the second connecting piece 520 and moves away from the shell liquid outlet hole 110, and then the liquid outlet end of the pump head 310 is exposed; the first connecting piece 510 continues to be driven by the driving device 200 to move, the straight surface part 542 abuts against the second connecting piece 520, and the liquid outlet baffle 550 is relatively fixed on the shell 100 with the second connecting piece 520, that is, when the straight surface part 542 abuts against the second connecting piece 520, the second connecting piece 520 no longer moves. It can be understood that when the driving end of the driving device 200 moves from the initial position to the jacking position, the inclined surface part 541 abuts against the second connecting piece 520 and drives the second connecting piece 520 to move, and then the straight surface part 542 abuts against the second connecting piece 520, and the liquid outlet baffle 550 is relatively fixed on the shell 100 with the second connecting piece 520. By setting the side surface of the connecting boss 540 as the inclined surface part 541 and the straight surface part 542, the characteristics of the pump head 310 of the liquid bottle 300 are more in line with, which not only guarantees smooth liquid outlet, but also saves the liquid outlet time to a certain extent. Specifically, in the first compression distance of the entire compression stroke of the pump head 310, the liquid outlet does not occur, at this time the inclined surface part 541 abuts against the second connecting piece 520 and drives the second connecting piece 520 to move, the liquid outlet baffle 550 moves with the second connecting piece 520 and moves away from the shell liquid outlet hole 110 to expose the liquid outlet end of the pump head 310; during the process of moving the liquid outlet baffle 550 away from the shell liquid outlet hole 110, the liquid outlet action is not affected. When the liquid outlet baffle 550 is completely moved away, the first connecting piece 510 continues to be driven by the driving device 200 to move, at this time the straight surface part 542 abuts against the second connecting piece 520, and the second connecting piece 520 and the liquid outlet baffle 550 no longer move, and at the same time the pump head 310 continues to be compressed to liquid outlet. After the liquid outlet is completed, the driving end of the driving device 200 is retracted, the first connecting piece 510 can move and reset, and the liquid outlet baffle 550 can reset with the second connecting piece 520, so that the liquid outlet baffle 550 blocks the liquid outlet end of the pump head 310. Compared with moving the liquid outlet baffle 550 first and then compressing the pump head 310, the liquid outlet device described in the embodiment moves the liquid outlet baffle 550 and compresses the pump head 310 at the same time by setting the side surface of the connecting boss 540 as the inclined surface part 541 and the straight surface part 542, which not only guarantees smooth liquid outlet, but also effectively saves the liquid outlet time and improves the liquid outlet efficiency to a certain extent.

Alternatively, the number of the first shaft seats 120 is two. Through the first shaft seats 120, it is convenient for the shell 100 to support the first connecting member 510, and it is also convenient for the first connecting member 510 to be in sliding connection with the shell 100.

[0103] Alternatively, the first connecting member 510 is sleeved with a first elastic member 511 and a first blocking piece 512; the first elastic member 511 and the first blocking piece 512 are located between two of the first shaft seats 120; alternatively, the first blocking piece 512 is in fixed connection with the first connecting member 510.

[0104] Alternatively, when the driving end of the driving device 200 moves from the initial position to the jacking-in-position, the first blocking piece 512 moves with the first connecting member 510 and compresses the first elastic member 511; that is, the first elastic member 511 is compressed under the action of the first blocking piece 512 and one of the first shaft seats 120.

[0105] Alternatively, when the driving end of the driving device 200 moves from the jacking-in-position to the initial position, the first elastic member 511 can drive the first blocking piece 512 to reset, so that the first connecting member 510 resets with the first blocking piece 512, and then the connecting boss 540 resets with the first connecting member 510, so as to cancel the action force of the connecting boss 540 on the second connecting member 520.

[0106] Referring to Figures 7-10 As shown, in an optional solution of the embodiment, the shell 100 is provided with second shaft seats 130 in sliding connection with the second connecting member 520; the number of the second shaft seats 130 is at least two; for example, the number of the second shaft seats 130 is two, three or five, or other numbers. Alternatively, the number of the second shaft seats 130 is two.

[0107] Alternatively, the second connecting member 520 is sleeved with a second elastic member 521 and a second blocking piece 522; the second elastic member 521 and the second blocking piece 522 are located between two of the second shaft seats 130; alternatively, the second blocking piece 522 is in fixed connection with the second connecting member 520.

[0108] Alternatively, when the driving end of the driving device 200 moves from the initial position to the jacking-in-position, the second blocking piece 522 moves with the second connecting member 520 and compresses the second elastic member 521; that is, the second elastic member 521 is compressed under the action of the second blocking piece 522 and one of the second shaft seats 130.

[0109] Optionally, when the driving end of the driving device 200 moves from the jacking position to the initial position, the second elastic member 521 can drive the second blocking piece 522 to reset, so that the second connecting member 520 resets with the second blocking piece 522, and then the liquid outlet baffle 550 resets with the second connecting member 520, until the liquid outlet baffle 550 blocks the liquid outlet end of the pump head 310.

[0110] Referring to Figure 5 Optionally, in the alternative of the embodiment, the shielding device 500 further comprises a third connecting member 530; the driving end of the driving device 200 is connected to the first connecting member 510 through the third connecting member 530.

[0112] Optionally, the axial direction of the first connecting member 510 intersects with the axial direction of the second connecting member 520; for example, the axial direction of the first connecting member 510 is perpendicular to the axial direction of the second connecting member 520.

[0113] Optionally, the driving device 200 can drive the first connecting member 510 to move along the axial direction of the first connecting member 510 through the third connecting member 530, so that the connecting boss 540 abuts against the second connecting member 520 and drives the second connecting member 520 to move along the axial direction of the second connecting member 520, and then drives the liquid outlet baffle 550 to move away from the shell liquid outlet hole 110, and then exposes the liquid outlet end of the pump head 310. The first connecting member 510 can move along the axial direction of the first connecting member 510, and the second connecting member 520 can move along the axial direction of the second connecting member 520, which further facilitates the transmission of the driving force of the driving device 200.

[0114] Referring to Figures 2-5 and Figure 11 Optionally, in the alternative of the embodiment, the driving end of the driving device 200 is connected to the bottom of the liquid bottle 300 through the weighing device 400. The weighing device 400 can weigh the liquid bottle 300, and the remaining amount of the liquid in the liquid bottle 300 can be calculated according to the change of the weight.

[0115] Optionally, the shielding device 500 has a shielding driving connection end; the driving end of the driving device 200 is connected to the shielding driving connection end; that is, the shielding driving connection end is one end of the third connecting member 530 away from the first connecting member 510.

[0116] The weighing device 400 is located between the shielding driving connection end and the liquid bottle 300; by adopting the design, the interference of the shielding device 500 on the weighing device 400 can be reduced or avoided, and the weighing device 400 can more accurately monitor the remaining amount of the liquid in the liquid bottle 300.

[0117] Optionally, the weighing device 400 is detachably connected with the driving end of the driving device 200, so as to facilitate the maintenance and assembly of the weighing device 400 and the driving device 200.

[0118] As shown in Figure 11 , optionally, the driving end of the driving device 200 is connected with a driving connection piece 210, and the position of the driving connection piece 210 on the driving end of the driving device 200 can be adjusted to change the initial distance between the driving connection piece 210 and the fixed end of the driving device 200.

The first weighing shell 410 abuts against the bottle bottom of the liquid bottle 300, and the second weighing shell 420 is detachably connected with the driving connection piece 210. By detachably connecting the second weighing shell 420 with the driving connection piece 210, when the position of the driving connection piece 210 on the driving end of the driving device 200 is adjusted, the driving connection piece 210 can be moved away from the second weighing shell 420, so as to facilitate the position adjustment of the driving connection piece 210 and avoid the influence of the second weighing shell 420 on the position adjustment of the driving connection piece 210.

[0120] As shown in Figure 13 , in an optional scheme of the embodiment, the liquid outlet device further includes a control device 600 fixedly connected with the shell 100; the control device 600 is electrically connected with the driving device 200; by the control device 600, the whole liquid outlet device can be controlled.

[0121] As shown in Figure 1 , Figure 12 and Figure 13As shown, in an optional solution of this embodiment, a liquid discharge reset button 140 electrically connected to the control device 600 is provided on the housing 100; the control device 600 is configured to receive a liquid discharge press signal from the liquid discharge reset button 140, and correspondingly control the drive device 200 to squeeze the pump head 310 of the liquid bottle 300, and drive the shielding device 500 away from the liquid discharge hole 110 of the housing. The liquid discharge device can be manually controlled to discharge liquid through the liquid discharge reset button 140. For example, the liquid discharge press signal is a long press for at least 3 seconds. When the liquid discharge reset button 140 is manually pressed for at least 3 seconds, the control device 600 controls the drive device 200 to drive the shielding device 500 away from the liquid discharge hole 110 of the housing, and squeeze the pump head 310 of the liquid bottle 300, to achieve a single liquid discharge.

[0122] See also Figure 1 、 Figure 12 and Figure 13 As shown, in an optional scheme of this embodiment, a residual liquid indicator light 150 electrically connected to the control device 600 is provided on the shell 100; the residual liquid indicator light 150 is configured to display information about the liquid remaining in the liquid bottle 300; for example, when the liquid remaining in the liquid bottle 300 is sufficient, the residual liquid indicator light 150 is always on; when the liquid remaining in the liquid bottle 300 is less and reaches the warning value, the residual liquid indicator light 150 slowly alternates between light and dark; when there is no liquid at all in the liquid bottle 300, the residual liquid indicator light 150 goes out.

[0123] Optionally, the remaining liquid indicator light 150 is integrated with the liquid discharge reset button 140 , that is, the liquid discharge reset button 140 is a button with an indicator light.

[0125] Optionally, the control device 600 is configured to receive a weight reset press signal from the liquid discharge reset button 140. Currently, the weights of different types of liquid bottles 300 are rarely the same. The liquid discharge reset button 140 can be used to reset the weight of the current liquid bottle 300 in the control device 600. For example, the weight reset press signal is to quickly press the button five times. Place an empty liquid bottle 300 on the weighing device 400 and quickly press the button five times. The control device 600 receives the weight reset press signal and replaces the previously set empty bottle weight with the current empty bottle weight. After the replacement is complete, the indicator light flashes rapidly several times (this indicator light can be the remaining liquid indicator light 150 or another indicator light), indicating that the operation was successful. The liquid discharge press signal and the weight reset press signal are different.

[0126] See also Figure 7 、 Figure 9 and Figure 13As shown, in an optional solution of this embodiment, a cleaning indicator light 160 electrically connected to the control device 600 is provided on the housing 100; a timer 170 electrically connected to the control device 600 is provided within the housing 100; the timer 170 is configured to send a timer signal to the control device 600 when a preset timer is reached, and the control device 600 correspondingly disconnects the circuit of the cleaning indicator light 160 so that the cleaning indicator light 160 is not illuminated; the cleaning indicator light 160 is used to remind the user that the liquid dispensing device has not discharged liquid for a long time. If no liquid is discharged within the preset timer, the liquid remaining at the liquid outlet of the pump head 310 may solidify, which may affect the liquid dispensing operation and food safety, and the liquid outlet of the pump head 310 needs to be cleaned.

[0127] To clean the liquid outlet of the pump head 310, you can manually remove the shielding device 500, that is, manually remove the liquid outlet baffle 550. After cleaning is completed, you can press the liquid outlet reset button 140 to indicate that the cleaning is completed and the cleaning indicator light 160 lights up. Figure 13 As shown, in an optional solution of this embodiment, the control device 600 is configured to receive a cleaning press signal from the liquid discharge reset button 140, and to connect a corresponding circuit to the cleaning indicator light 160 so that the cleaning indicator light 160 lights up. In this embodiment, the lighting of the cleaning indicator light 160 indicates that cleaning is complete; the off-lighting of the cleaning indicator light 160 indicates that no liquid has been discharged for a long time and the liquid outlet end of the pump head 310 needs to be cleaned. Among them, the liquid discharge press signal, weight reset press signal and cleaning press signal of the liquid discharge reset button 140 are different from each other. By multiplexing the liquid discharge reset button 140 and adopting different signals such as the liquid discharge press signal, the weight reset press signal and the cleaning press signal, costs are effectively saved and the structure of the liquid discharge device is simplified.

By multiplexing the liquid outlet reset button 140, different signals such as the liquid outlet pressing signal, the weight reset pressing signal and the cleaning pressing signal are adopted, the cost is effectively saved, and the structure of the liquid outlet device is simplified.
